No need to cover if you just spray the OE tin can casing with ACF 50 once every couple of years. Takes 15 secs and about 20p a treatment Wink

Just to update this older thread.

ACP cover was fitted and the correct vacumm must have been achieved as everything works as it should.
I would definitely go down this route again and only replace a pump if knackered - not just for a new cover.

On one of these threads i saw someone asking about 997.2 tandem pump designs/shapes.


997.2's only have a vacuum pump, That's around £113 from Porsche. It does get corroded like the tandem oil pump on the 997.1 and will have the same effects if it starts to corrode through. I.E brake pressure being lower/non existent!


I've just changed mine for preventative maintenance, Was easy and cheap enough. If the other one had done nearly 10 years on the car, I'm sure this one will make another 10, especially as i don't drive it in winter.

I hadnt realised they were so cheap for the gen2 , thats now on my list to do as a preventative measure.
thanks Neil for the heads up Thumb Thumb
